The adjustable wrench set includes 6, 8 and 10 inch long wrenches to give your tool box much needed versatility and ability. Made with quality forged alloy steel. The tools in this Craftsman adjustable wrench set have wide beam handles for more comfort and control. They feel great in your hands strong enough for when you need some torque, but light and balanced when you need precision. The precision-broached, hardened steel jaws hold their grip on nuts and bolts. And it doesn't matter whether your application calls for a standard- or metric-sized tool. With these versatile wrenches, you simply turn the adjustable thumbwheel to open and close the jaws.
